I purchased this new, but ended up using my Silent Brass more often, so I've only used this three times. I've kept it in its mute case since then, so it's in good condition. You can adjust the resistance by using the removable inner tube. If you're looking for a practice mute, how about this one? ~Excerpt from the product website~ Practice mutes often prioritize sound dampening and playing feel. However, the most important thing is the comfort of the sound you hear. In 2013, the handmade practice mute 《okura+mute》 was born, which doesn't compromise your playing technique and can potentially help you improve. It quickly spread to players around the world, and inquiries from all over the world continue to pour in. We wanted more players to experience it, so we created a new okura+mute. The okura+mute provides excellent sound dampening and a comfortable feel that makes you want to keep playing. #PracticeMute #okuraMute
